Question

I have a field with temporal type as Timestamp to save both date and time to the database.

@Temporal(TemporalType.TIMESTAMP)
@Column(name="date", nullable=false)
private Date date;

But when displaying the value to the user, I just want to show date part and truncate time part. I tried this but I get ParseException probably because of the Nanosecond part of the Hibernate Timestamp.

 SimplDateFormat sd = new SimpleDateFormat("MM/dd/yyyy");
 return sd.parse(date.toString());

So how do I retrieve just date from Hibernate Timestamp? Thanks

Answer 1

Just format the date object. The toString method isn’t guaranteed to give you a string in a format that can then be parsed.

String dateStr = sd.format(date);

That will give you a date string in MM/dd/yyyy format that you can then convert back into a Date.

Date fancyNancy = sd.parse(dateStr);

Run this code and verify it prints out the day, month and year with no time.

try {
    Date d = new Date();
    SimpleDateFormat df = new SimpleDateFormat("MM/dd/yyyy");
    System.out.println("Original Date: " + d);
    System.out.println("Formatted Date: " + df.parse(df.format(d)));
} catch (Exception e) {
    e.printStackTrace();
}
